A physics educator whose joint classroom experiment uses a <cloud chamber> to connect particle detection with observable condensation. The chamber’s temperature gradient creates vapor that condenses along ionized tracks. Illumination at a low angle reveals those tracks, letting students investigate naturally occurring <cosmic rays> with simple optical and thermal equipment.<Bringing Particle Physics to Life: Build Your Own Cloud Chamber by Francisco Barradas-Solas and Paloma Alameda-Meléndez>[Assembly and operation: dry-ice base, warm upper region and low-angle illumination]{ref}
